Water and health: why drink enough
I. The importance of water for the human body
Water is the basis of life. It is approximately 55-78% of the body weight of an adult, depending on age, gender and body composition. In newborns, this figure is even higher, reaching 80%. Water is involved in almost all physiological processes occurring in the body, ensuring its normal functioning. Without water, a person can live only a few days, while without food – several weeks.
A. The main functions of water in the body:
-
Transport of substances: Water serves as a universal solvent, transferring nutrients, oxygen, hormones and other important compounds to cells and tissues. It also helps to remove metabolism products, such as carbon dioxide and urea, from the body.
-
Thermoregulation: Water has high heat capacity, which allows it to effectively adjust body temperature. When it is hot, the body emits sweat, which, evaporating from the surface of the skin, cools the body.
-
Participation in metabolic processes: Water is necessary for many chemical reactions occurring in the body, including hydrolysis, which breaks down complex molecules into simpler ones.
-
Lubrication of the joints: The synovial fluid filling the joints contains a large amount of water. It provides smooth sliding of the joint surfaces and protects the cartilage from wear.
-
Protection of organs and tissues: Water is an important component of cerebrospinal fluid, which protects the brain and spinal cord from injuries. It is also part of an amniotic fluid surrounding the fetus during pregnancy.
-
Maintaining electrolyte balance: Water is involved in maintaining the necessary concentration of electrolytes, such as sodium, potassium and chlorine, which play an important role in transmitting nerve impulses and muscle contraction.
-
Normalization of blood pressure: Adequate water consumption helps to maintain a normal volume of blood, which, in turn, helps to maintain healthy blood pressure.
-
Skin health: Water provides skin hydration from the inside, supporting its elasticity and elasticity. The lack of water can lead to dryness, peeling and premature skin aging.
-
Maintaining the normal operation of the digestive system: Water is necessary for normal digestion. It helps to soften food, facilitating its advancement on the digestive tract, and prevents constipation.
-
Maintaining kidney function: Water helps the kidneys remove waste and toxins from the body. Insufficient water consumption can lead to the formation of stones in the kidneys and other kidney problems.
B. Factors affecting the need for water:
The need for water is individual and depends on many factors, including:
-
Age: Children and elderly people are more susceptible to dehydration.
-
Floor: Men usually need more water than women, due to a larger body size and larger muscle mass.
-
The level of physical activity: Physically active people lose more water with later and need to replenish it.
-
Climate: In hot and wet climate, the need for water increases.
-
Health status: Some diseases, such as diabetes and kidney diseases, can increase the need for water.
-
Diet: The use of a large amount of salt, caffeine or alcohol can increase the need for water.
-
Pregnancy and breastfeeding: Pregnant and lactating women need more water to maintain their health and health.
II. Symptoms of dehydration
Dehydration is a condition that occurs when the body loses more fluid than it receives. Even a slight dehydration can adversely affect physical and mental activity.
A. Early signs of dehydration:
-
Feeling thirst: This is the most obvious sign of dehydration. However, it is important to remember that a feeling of thirst may appear even when the body has lost a significant amount of fluid.
-
Dry mouth and throat: The lack of saliva leads to dry mouth and throat.
-
Dark urine: The color of urine is a good indicator of hydration. Light urine speaks of sufficient water consumption, and dark – about possible dehydration.
-
Rare urination: If you rarely go to the toilet in a small way, this may be a sign that you do not drink enough water.
-
Headache: Dehydration can cause headache, since the brain is sensitive to a change in fluid level in the body.

Fatigue and weakness: Dehydration can reduce energy level and cause a feeling of fatigue and weakness.
-
Dizziness: The lack of fluid can reduce blood pressure and cause dizziness.
-
Dry skin: The skin can become dry and less elastic.

Convulsions: In severe cases, dehydration can cause convulsions.
-
Lack of urination: This indicates that the kidneys have ceased to function properly.
C. dehydration in children and the elderly:
Children and elderly people are more vulnerable to dehydration. In children, this is associated with a higher metabolism rate and a larger area of the surface of the body in relation to body weight. In older people, a sense of thirst can be weakened, and they may forget to drink enough water.
